Battery life on linux (alien.top)

Hello people, Can you please provide the average battery life you're getting on linux alongside your framework model, your distro and usage? I'm 100% sure the fw 13 will be my next compute but I've seen a lot of difference between the battery life people are getting, so I want to see if there's a pattern.

2-4 hours for me on Fedora (AMD). This is with media consumption (video mainly) and I haven't tested it for productivity yet cause uni is on break. I've been trouble shooting this to try and get better performance because I have a feeling Flatpaks may not be as optimised for hardware acceleration. For the most part though, general web browsing and whatnot does not seem to hit the battery at at all really.

    I see the same pattern on my AMD with Linux outside of flatpaks (battery usage for text editing is good, but for videos it's not great), so flatpaks are probably not the problem. I guess the GPU uses too much energy when decoding video - hopefully this is a driver problem and not how the hardware is inherently.

    I have a similar issue, so I looked and it also happens on 7840U Thinkpads, so apparently video acceleration isn’t quite optimized yet on Linux for the 7040 CPUs. Hopefully future kernel versions solve this.
